UNITED STATES PATENT OEEIGE.

CHARLES CAMP, OF BUFFALO,-NEW YORK.

IMPROVEMENT IN ELEVATORjBUCKETS.

Specification forming part oi' Letters Patent No. 58,595, dated October 9, i866.

To all whom it may concern:

Be it known that I, CHARLES CAMP, of Butfalo, in the county of Erie and State or" New York, have invented a new and useful Improvement in Elevator-Buckets; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists in the combination of indiavrubber 0r other equivalent elastic, eXible, or pliable material with the supporting-frame of an elevator-bucket, for the purpose oi' rendering it elastic or fle-Xible, so that it can either spring past an obstruction and regain its original form Without breaking, or be forced into shape by the action of scooping up the grain, thus preventing the breaking of buckets or belt, which often occurs with the metallic buckets now in common use.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my bucket in any of the usual forms. The frame, or that part which supports the bucket, and which dips into and scoops the grain during the action of elevating, and which is most exposed to wear, is made of sheet or cast metal. The lower part or body of the bucketis made of either india rubber, leather, cotton, or wool, either woven or knit.

In said drawings, Figure l represents a side elevation; Fig. 2, a perspective view, and Fig. 3 a view ot the bucket as bent out of shape by an obstruction.

A is the supporting-frame, to which the elastic or tlexibe part B of the bucket is attached. It is fastened to the driving-belt, a part of which is shown at E, in the usual manner, by means of bolts or screws, and is driven by the usual machinery for elevating. In buckets of large size it is ot'ten necessary to fasten a stay across theinside ot' the frame to give it sufficient strength. In passing an obstruction they may be bent out of their usual shape without injury, somewhat similar as shown in Fig. 3, but will immediately regain it after passing.

What I cla-im as my invention, and desire to secure by Letters Patent, is-

l. The elastic or leXible elevator-bucket composed of the materials described, or the equivalent thereof.

2. In combination therewith, the metallic rin] A, as and for the purposes specified.
